Teeth names are created by a combination of 4 different characteristics: 1  The jaw where they are located: upper and lower (alternatively the terms maxillary and mandibular can be used) 2  The side of the face: left and right.  The type of tooth: incisor, canine, premolar, and molar.
Vampire bats are members of the New World Leaf-nosed bats, the Phyllostomidae. All three species of living vampire bats occur in South and Central America. Fossils of three other species reveal that several thousand years ago vampire bats were more widespread.
The bats usually live in colonies ranging from 20 to 100 individuals although much larger colonies (up to 5,000) have been reported. Desmodus rotundus roosts in moderately lighted caves with deep fissures, and in tree hollows. Vampire bats can also be found in old wells, mine shafts, and abandoned buildings.
